Objective To study the clinical analysis in the neonatal hypoxic-ischemic encephalopathy (HIE)for evealuation of the severity of brain injury and prognosis. Methods The manifestation,laboratory findings,outcomes of 117 HIE were analyzed. Results Manifestations of HIE in 117 infants included 3 groups(minor level,moderate level,severe level). There was no significant difference in the weight and gestation-age among 3 groups.Scores of Apgar lowing,which Was marked in the severe level(P＜0.01). There was significant difference in the level of pH and PaCO2(P＜0.01). There was significant difference in the level of blood GLU and BE reduced aboviusly in the severe level,and in the level of BUN,CK-MB,CK increased aboviusly in the moderate and severe level,among all(P＜0.01). 69 patients were taked CT on the brain,the abnormal rate of which was 82.6%. The abnormal rate of CT on the brain increased 100% changing with the severity of brain injury on HIE especially in the moderate and severe level. Conclusion The prognosis of the minor level of brain injury on HIE is the best. The prognosis of the moderate-level group who was treated reasonably and enough,is better mostly.

Fluorescent technology is widely used in many fields due to its high sensitivity. However, the direct quantification of one target analyte in complex system is still difficult to be achieved when using the traditional fluorescent method without any pretreatment separation procedure. This is due to the fact that serious overlapping of fluorescence spectra often occurs, mainly originating from natural interferences in complex sample backgrounds, or the interferents with similar structures to a target analyte, particularly in the simultaneous analysis of multi-components samples. The rapid development of modern analytical instruments and three-way data collection techniques has led to a resurgence of interest in the development of chemomet-rics-based analytical strategies, which might light a new avenue to simple experimentation using“mathematical separation” as a replacement or enhancement of“physical or chemical separation” of uncalibrated background or interferents. These methods can offer a highly attractive property, called“second-order advantage”, which allows for the direct and rapid determination of a single target component or simultaneous determination of multiple target components in complex samples, even in the presence of uncalibrated interferences. The property has been a hotspot in the current chemometric domain, and was successfully employed for many applications, such as pharmaceuticals, biological, food, environmental analysis and so on.

Objective To test the inhabiting effect of Lactobacillus acidophilus on E.coli O157: H7 in intestinal colonization and explore its mechanism. Methods The suppressive effects of Lactobacillus acidophilus against E.coli O157:H7 adhering to Ht29 cells were carried out by competition , exclusion and replacement as-says. Furthermore, we evaluated the cytokine levels of IL-4, IL-12, and INF-γ in serum of mice. In addition, E.coli O157:H7 fecal shedding was monitored and the pathological changes of intestines were observed in mice. Results The competition, exclusion and replacement assays showed Lactobacillus acidophilus inhibited E.coli O157:H7 adhering to Ht29 cells. In vivo, the mice of treatment group were induced significantly higher level of IL-4, IL-12, and INF-γ, though prevention group induced IL-12 only. Fifteen days after E.coli O157:H7 infec-tion, there were 8 mice (80%) in prevention group and 5 mice (50%) in treatment group stopped shedding. Moreover, the pathological changes of intestines of both prevention group and treatment group appeared normal , but control groups showed seriously damaged in intestinal villus. Conclusion Lactobacillus acidophilus inhibits E.coli O157:H7 in intestinal colonization and the preventative effect was better than treatment effect. Thus , Lac-tobacillus acidophilus can be used for E.coli O157:H7 in prevention and treatment infection as probiotics.

Objective:To analyze the association between waist circumference (WC) and ischemic stroke (IS).Methods:The data for the present study were from the prospective cohort study of China Kadoorie Biobank in Qingdao. Using baseline information and IS events of the participants, the Cox proportional hazard regression model and restricted cubic spline (RCS) were used to analyze the association between WC and IS.Results:A total of 33 355 participants were included in the study, with 302 008.88 person-years of follow-up. A total of 1 093 new cases of IS were observed. Multivariate Cox proportional hazard regression model analysis showed that compared to the respondents with normal WC (male <85.0 cm, female <80.0 cm), respondents with excessive WC (male ≥85.0 cm, female ≥80.0 cm) had a 78% higher risk of IS incidence [hazard ratio( HR)=1.78, 95% CI: 1.51-2.10], and the risk increased by 72% ( HR=1.72, 95% CI: 1.40-2.12) and 83% ( HR=1.83, 95% CI: 1.40-2.39) in men and women. According to the RCS, the increase in WC and the risk of IS showed an "S" trend of nonlinear dose-response relationship. Conclusions:The risk of IS would increase with the WC. Keeping a normal WC is important for preventing IS.

Objective: To understand the fruit consumption of adults of Qingdao and examine the association between fruit consumption and stroke. Methods: We analyzed baseline data and stroke incidence of the participants who were aged 30-79 years and had been enrolled into the China Kadoorie Biobank (CKB) study from Qingdao city. Cox proportional hazards regression model was conducted to estimate the association of fruit consumption with risk of stroke. Results: A total of 35 509 participants were investgated in the baseline survey. Ratio of male to female was 1∶1.27, and the average age was (50.3±10.2) years. Respondents with higher frequency of fruit consumption were younger, more women, with higher education level and higher income (P<0.05). A total of 1 011 new cases of stroke were observed, with a stroke incidence of 387.63/100 000 person-years. Multivariate Cox regression analysis showed that fruit consumption had a protective effect on stroke incidence. Compared to the respondents who never consumed fruit, respondents who consumed fruit more than 4 days per week had a 44% lower risk of stroke incidence (HR=0.56, 95%CI: 0.50-0.62, P<0.05), and the risk reduced by 46% (HR=0.54, 95%CI: 0.46-0.64, P<0.05) and 42% (HR=0.58, 95%CI: 0.52-0.69, P<0.05) in male and female, respectively. Further adjustment for WC, BMI, SBP and random blood glucose did not change the association. Conclusion Increasing fruit consumption can effectively decrease the risk of stroke. People should increase fruit consumption advisably to set up reasonable and healthy dietary habits.

Objective: To evaluate the correlation between alcohol consumption and obesity in adults in China. Methods: The information about alcohol consumption were collected at the baseline survey of the China Kadoorie Biobank. The general obesity and central obesity were defined by BMI and waist circumference (WC) respectively. Logistic regression model was employed to examine the relationship of drinking behavior with general obesity and central obesity. Results: A total of 249 873 adults were included. A J-shaped relationship was observed between alcohol consumption and obesity measurement index (BMI and WC) in men. Compared with non-drinkers, the proportion of general obesity and central obesity were lower in light drinkers (men: OR=0.65, 95%CI: 0.59-0.71 and OR=0.93, 95%CI: 0.88-0.98; women: OR=0.77, 95%CI: 0.65-0.91 and OR=0.89, 95%CI: 0.80-0.99). In men, the proportion of general obesity and central obesity was highest in heavy drinkers (OR=1.21, 95%CI: 1.12-1.32; OR=1.33, 95%CI: 1.27-1.40). BMI and WC were higher in those with a drinking frequency of 3-5 d/week, with largest of proportion of central obesity (men: OR=1.23, 95%CI: 1.16-1.31; women: OR=1.13, 95%CI: 0.99-1.28). The risk for central obesity in men who began drinking every week before 20 years old was 1.24 times higher than non-drinkers (95%CI: 1.16-1.33). Those who drank beer had lower proportion of general obesity (men: OR=0.74, 95%CI: 0.67-0.82; women: OR=0.54, 95%CI: 0.43-0.68). Conclusion The proportion of obesity was lower in light drinkers but higher in heavy drinkers; and the earlier drinking started, the higher the risk for obesity was.
